#### Clothesline numbers

This is a collection of numbers you can use to do an activity with a length of rope and some pegs. Two students hold each end of the rope (or put it on the floor for smaller groups) and other students peg their number on the line (start with easy ones like 1/2 or 0.5 - which can easily be checked by folding rope in half). There are a mixture of numbers so you differentiate easily. Super challenge: place x and ask then ask where would 2x be placed. I have also made smaller sized numbers if you want to give each student their own numbers (print on coloured paper to help you differentiate)

#### Bounds and Volume Reasoning Tasks

Several tasks all based on a GCSE question about upper and lower bounds for 3D shapes. These tasks are designed to improve students’ mathematical reasoning and were created as part of the Mathematical Reasoning at GCSE project run by Cambridge Maths Hub. The tasks vary in difficulty. They are not intended to be used all together; just pick and choose one or two suitable ones for your class.

#### PE Dept - Athletics - How To Measure Throwing Events (Discus / Javelin / Shot)

Athletics - How To Measure Throwing Events (Discus / Javelin / Shot Put) - is a set of three help cards that I produced using SMART Notebook in order to help colleagues / students measure their throws accurately. The cards can be exported from SMART Notebook as JPEG picture files. The help cards have been used in schools and annually at our District Schools’ Athletics Championship.

#### Andy's SSDD Questions 3

This idea is from Craig Barton and is an excellent one (check them out his at website); essentially it is four questions based on the same information. There are four here which use volume, ratio, Pythagoras, bearings, measures, area and perimeter, speed, percentages and bounds as well as other topics. This really should create discussion and a deeper understanding of the topics covered on top of ensuring that students actually read the question. I hope these are worthy! I will be using these as starters or plenaries.

#### Maths Investigation using ICT
